Many round-based chaotic image encryption algorithms employ the permutation-diffusion structure. Schemes using this structure have been found insecure when the iteration round is equal to one and the secret permutation of some existing ones can be recovered even a higher iteration round is adopted. In this paper, we present a single round permutation-diffusion chaotic cipher for gray image, in ...

BACKGROUND The heat produced by provisional restoration materials may injure the dental pulp. This study measured and compared peak temperatures during polymerization of 5 materials used in the fabrication of provisional restorations. METHODS The tested materials were 2 self-curing resins (Integrity and Protemp) and 3 dual-cure resins (Iso-Temp, TCB Dual Cure and Provipont DC). A mould the si...

The major disadvantage of cement-retained implant-supported fixed partial dentures (FPDs) is difficulty in retrievability. The retentive strengths of the provisional luting agents usually employed in these cases are therefore an important consideration. This study evaluated the cement failure loads of 4 provisional luting agents used for the cementation of FPDs supported by 2 implants or 4 impl...

This search aim to study the feasibility of hydro-desulfurization (HDS) gas oil in fixed bed reactor by using economic support catalyst alumina meta kaolin (AMK) under various operating condition, i.e. Temp. (240−320 ◦C), Press. (3–12 bar), WHSV (2–6 h−1) at H2/HC ratio (50 vol./vol.). The was prepared from Iraq and characterization scanning electron microscopy (SEM), energy dispersive X-ray an...

The SLC51 organic solute transporter family of transporters is a pair heterodimeric proteins which regulate bile salt movements in the small intestine, duct, and liver, as part enterohepatic circulation [2, 5, 1]. OSTα/OSTβ also expressed steroidogenic cells brain adrenal gland, where it may contribute to steroid sulphate movement [6]. Bile acid transport suggested be facilitative independent s...

One of the most popular approaches to parameter adaptation in hidden Markov model (HMM) based systems is the maximum likelihood linear regression (MLLR) technique. In our previous work, we proposed factored MLLR (FMLLR) where an MLLR parameter is defined as a function of a control parameter vector. We presented a method to train the FMLLR parameters based on a general framework of the expectati...

Domain-wall free energy sigmaF, entropy sigmaS, and the correlation function C(temp) of sigmaF are measured independently in the four-dimensional +/-J Edwards-Anderson (EA) Ising spin glass. The stiffness exponent theta, the fractal dimension of domain walls d(s), and the chaos exponent zeta are extracted from the finite-size scaling analysis of sigmaF, sigmaS, and C(temp), respectively, well i...
